New York is one of the last large American cities to have some of its policemen on horseback.The New York Police have 170 horses working in cerain parts of the city.The horses are expensive to feed,but it is even more expensive to take care of them.Because the hores must walk on the steets,they need special horseshoes.In fact,they need more than 8,000 of them each year.Every police horse in New York gets new shoes every mooth.Keeping these shoes in good repair is the job of six blacksmiths.There are only about thirty-five of these blacksmiths in the whole United States.

纽约是美国大城市中最后几个有骑马警察的城市之一。纽约警方拥有170匹马工作在某些固定区域。喂马的食物是一笔大支出，但照顾好这些马更费钱。由于这些马得在大街上走，所以它们需要特制的马蹄。事实上，每年大约需要8000多只马蹄。纽约的每匹警马每月都要换新马蹄。保证这些马蹄保持良好状态是6个铁匠的职责。整个美国像这样的铁匠人数大约也只有35人。
